Day 5: Approach to the Inmost Cave – Integrating a Photoresistor

from machine import Pin, ADC
import time

# Initialize the LED and photoresistor
led = Pin(15, Pin.OUT)
photoresistor = ADC(Pin(26))

while True:
  # Read the value from the photoresistor
  light_level = photoresistor.read_u16()

  # Print the light level (optional for debugging)
  print(light_level)

  # Control the LED based on the light level
  if light_level < 20000:
    led.on()
  else:
    led.off()

  # Delay for a short period
  time.sleep(0.5)
